Yes I have done that on a 3 element SteppIR. It turns a mediocre performer
into a beam with a great pattern.
I use 4NEC2. Could send the file I used and you could modify it for your
purposes. The main thing you would need to know is the fixed locations of the
existing elements. I DID NOT take into consideration physical effects (torque,
balance, etc) - just the electrical properties.
And for example I found that adding a passive reflector and leaving the
original reflector extended to its original setting does not deteriorate the
pattern.
